SEAT-SUPPORT FOR MOTOR-CYCLES.

Specification of Letters Patent.

Application filed April 2S, 1913.

Patented Mar. 1.7, 1914:.

Serial No. 764,006.

To all whom t may conce/rn.'

Be it known that I, vWlLLmivI H. BRADLEY, a citizen. of the United States, residing at Portland, in the county of lVIultnomah and State of Oregon, have invented certain new and useful Improvements in Seat-Supports :lor lvlotor-Gycles, ot' which the following a specification.

ihis invention relates to an improvement in seat supports 'for motor cycles, and has for its object to provide a support upon which two or more seats may be carried.

A further object is to provide a means by which said supports may yield in conformity to the movements of the yieldable saddle post.

rllhese and other objects are accomplished by means of the structure illustrated in the accoi'npanyin drawing', in which- Figure 1 is a rear elevation showing a portion of a motor cycle frame with my improvement mounted thereon. Fig. 2 is a side elevation showing the device as in use. Fig. 3 is a plan view of one member of the seat supports.

Referring to the drawing, 1 represents a pair ot horizontal seat supports, each having,r a broad base adapted to carry a seat 2, and from the inner side of each of the arms 1a, each pair having the angular portion 1b, eX- tends to and across the saddle post bar f1, the one lapping upon the other, and, by means of the upper and lower members 3 and 18 respectively, and the U-bolt 5, they are adjustably secured to said bar 4, and are adapted to rise and fall with it as it vibrates on its post 19, and the saddle post 21, which rests upon the spring 29. carried in the member 9.() of the diamond. From the outer end oit each support is a depending` portion 1c which is inwardly inclined, and which has formed on its terminal portion a bearing' lug' 8, each of which is adapted to receive the upper portion of the spring stay 3, which consists of a spring rod provided with an intermediate coil 14, and at its lower end is formed a bearing 15 adapted to engage and rest upon the horizontal member 1G of the diamond to which it is secured by means oit the bolt 17.

Upon the upper terminal oit each ot the spring stays is secured a collar (l by means et a set screw 10; and at a lower point is secured a similar collar 11, by means oi set screw 12. intermediate the collar 11 and the lfiearing lug 8 secured a spring 9 upon cach stay. rlhese sustain the Vweight ot the supports 1 together with the load carried by them, and they also allow the outer portion oit the supports to yield in conformity c to the motion of the saddle post upon its spring. The spring coil 111 serves a similar purpose. Between the collar (i and the bearing' 8 is interposed another spring 7, the purpose oi. which is to take up the recoil oi the larger spring 9 and the spring; 141 upon which the load is largely sustained.

The olli-set at 1b allows oil' the construction of seats at substantially the same height as the main structure; and the clamp oit' the stays upon the bar 16 oit the frame, permits an adjustment oi." the support thereon.

By the construction here shown there is provided a support having;- a resilient effect, which is yieldablc in conformity to the vi luatory movements ci the saddle post and which presents a neat and attractive appear-ance.

Having thus described my invention, what l claim, is-

1. A seat support for motor cycles and the like having' a yieldable saddle post, a saddle bar pivotally secured thereto, transverse `base members secured to said saddle bar, and a brace secured at each side to the lower portion oiu the 'trame and yieldingly united to its respective base member.

2. A seat support for motor cycles and the like having' a yieldable saddle post, a saddle bar pivotally secured thereto, transverse base members :uljustably secured to the saddle post, a springbrace secured at each side to the lower portion of the frame and means tor adjustably connectingthe terminal oi: each base member with its respecti ve brace.

3. The combination of a motor cycle trame with a yieldable saddle post, a saddle bar pivotally secured to the t'ramc and to said post` a pair oi trans\\'erse bars secured to the saddle bar` the terminals ot said bars .being turned down f'ardly at an acute angle, a stay rising from the horizontal portion ot the trame at each side having' a slidable connection with its respective transverse bar, and a spring element -lor positioning' and supporting' its respective bar.

4. The combination with a motor cycle 'trame of a yieldable saddle post, a saddle bar pivoted to the 'trame and to the post, a pair of transverse scat supports adjustably secured to the saddle bar,` a spring' stay tive seat support, a spring element upon each spring stay for positioning and sustaining its respective seat support7 means for adjusting said spring elements and means for taking up the recoil of the spring eiement.

In testimony whereof I affix my signature in presence of two Witnesses.
